Limit counter L4UFCNT
The Limit counter function L4UFCNT can be tested by connecting a binary input to
the counter and applying pulses to the counter. The speed of the pulses must not
exceed the cycle time of the function. Normally the counter will be tested when testing
the function that the counter is connected to, such as the trip function. When the
function is configured, test it together with the function that operates it. Trig the
function and check that the counter result corresponds to the number of operations.
